PHP ActiveRecord异常:找不到基表或视图 [英] PHP activerecord exception : Base table or view not found

问题描述

我正在尝试php活动记录，这是一个很棒的ORM，但是我处于停滞状态.

I am trying out php active record, it's a great ORM, however I am at a standstill.

几天来，我一直在四处浏览Google，博客，phpactiverecord文档以及statckoverflow，但未能找到解决此问题的合适方法.

I have looked around google, blogs, phpactiverecord documentation as well as statckoverflow for days but have not been able to come across a suitable solution to this problem.

我能够执行基本的CRUD(插入，获取，修改和删除)操作，但是一旦我使用静态的$ validates_uniqueness_of过滤器验证了对象属性，我就会得到

I am able to carry out the basic CRUD (insert,fetch, modify and delete) operations however as soon as i validate an object property using a static $validates_uniqueness_of filter, i get

致命错误:未捕获的异常'ActiveRecord \ DatabaseException'

Fatal error: Uncaught exception 'ActiveRecord\DatabaseException'

有消息

消息为"SQLSTATE [42S02]"的

异常"PDOException":基表或 找不到视图:1146中的表"test_ar.models'不存在" 325行上的C:\ wamp \ www \ test_AR \ AR \ lib \ Connection.php

exception 'PDOException' with message 'SQLSTATE[42S02]: Base table or view not found: 1146 Table 'test_ar.models' doesn't exist' in C:\wamp\www\test_AR\AR\lib\Connection.php on line 325

这是我完整使用的代码.

Here is the code i used in full.

<?php
$path_to_AR = "AR/"; 
include $path_to_AR . "activerecord.php"; 
ActiveRecord\Config::initialize(function($cfg) {
        $cfg->set_model_directory('model');
        $cfg->set_connections(
                        array(
                         'development' => 'mysql://root:asdf@localhost/test_ar',
                         'test' => 'mysql://username:password@localhost/test_database_name',
                         'production' => 'mysql://username:password@localhost/production_database_name'
                        )
                );
        });   

/*
class user extends ActiveRecord\Model 
{ 

  static $validates_presence_of = array(array('username', 'message' => 'Please supply a username')); //this works just fine
  static $validates_uniqueness_of = array(array('username'));//this line causes the PDO exception   

}
*/
$user = new user(); 

user::create((array('username'=>'mike','password'=>'test','created'=>time())));
$user::create(array('username'=>'mike')); //cannot even reach this line because of the exeption

平台和php版本

我正在使用php 5.3.4并使用每夜构建(2013年5月8日)，我几乎没办法解决这个问题.请提供有关纠正方法的建议.

I am using php 5.3.4 and using nightly build (May 8 2013) I have almost failed to get my head around this. Please advise on how to correct this.

在github上与一些开发人员讨论之后.看来这是一个错误.

After discussing it with a few developers on github. It seems this is a bug.

解决方法是在模型中创建自定义验证器

The work around was to create a custom validator in the model

public function validate() {
        if ($this->is_new_record() && static::exists(array('conditions' => array('username' => $this->username)))) {
            $this->errors->add('username', 'This username is already taken');
        }
}
